THERAPEUTIC GLOBE.

' Application filed February 20, 1926. Serial No. 89,704.

This invention relates to improvements in therapeutic apparatujs,and particularly to an evacuated lamp therefor I It has been found that in the various types of therapeutic apparatus in present use, which in most' casesuse reflected rays from a"source of light, that therfull benefit of the treatment cannot be obtained with these reflected rays as readily as where direct rays are used. f I i It is an objectof the present invention to provide a lamp constructionfor therapeutic apparatus inwhich the direct rays from the source of light may be obtained in their full force and with the rays extending in parallel relation from the filament.

1 A further object of the invention is to provide forfthe use oi direct rays in therapeutic treatments by providing a bulb construction in which theievacuated container for the, fila-,

ment has an enl'argedufilament chamber provided with-aflat'end portion and mounting the filamentinya planespa'ced and parallel with relation to'this slottedportion in order to prevent the distortion of the rays of light by the glass of the receptacle in the projection th'erethrough b'y refraction. 1

The invention comprehends numerous other objects residingin the'sp'ecial construction and arrangement of the evacuated container and filaments which are more particularly pointed. out in" the following detailed description and in theclaimsdirected to a preferred form of the invention, it being understood, however, that various changes "in the arrangement and construction of these parts may be made without departing from the spirit' nd scope-of the invention as herein set forth; I

In the drawing forming part of this appli-. cation: 7 p

Figure '1 illustrates a; side elevation of; the. lamp. constructionkand the shield applied 4 gitudinal section: p

Fig. '2 is..a: bottom elevational view of a structure as shown-in Fig.1. Fig. 3 is an enlarged detailtransverse section thru the 'lower end'of the evacuated 5 4 usually used with lamps of. this character thereto, portions being shown in vertical loi container and filament .showing the relation enlarged filament chamber a- This'bulb or globe 1 isnadaptedto receive the lead shield in therapeutic apparatus.

The 'end portion transversely of the axis of the evacuated container 1' indicated at 5 is formed of glass having a' uniform thick ness, and having the surface thereo'f'entirely flat-and ly1ng'w1thi'n a single plane.

The filament 6 is'formed ofalength' of strip material having the. flat' f'ac'e 7 disposed toward the fiat end portion f the evacuin a single plane infspaced parallel relation with respect to the fiatend s frasclearly ila'ted container and which is formed in zlgr' lustrated in Figs. 1 and 3; The opposite" ends of the filaments extend'as indicated at 8 through the base of the evacuated container, and are electricallyconnected -with' or globe so'as to 1 the terminals of the lam be properly inter-posed n an electric circuit connected'with a socket in which the lampmay be laced.

Suitable a ditional supporting wires 9 are used to support the filament intermediate the ends as clearly illustrated inorder that it may be maintained in'a plane parallel with the flat ends 5 of-the container.-

In operation it will be seen that the fiatface 7 of the filament strip isdisposed directly toward the flat end .5 of the container so that. a large number of parallel rays of light are -projected from the filament withinthe single plane in spaced parallelrela tion thru-the flatorplane ends 5 of the container, without distortion by refraction or in any other manner, sothat the rays leaving. theglobe' or bulb'"may be directed. in-ga Straight P Obtaining the direct action it of the rays in"thetreatmentfofthebody for; stimulating blood. supply, .the inhibition ofv the growth of bacteria, etc., and hastening the healing "of thepathological parts and producing asepsis;

This speci' 1' construction of therapeutic lamp or globe" for producing these results in v thev treatmentjof the body are more eflicient hnd will penetrate deeper through the direct.

parallel rays, given jo'fl' fromthe' flat surface of the fila'me'ntthat can be obtained with any p F J other form of container .or'filament construc- H' hus described'ouriiiventiom-what we claim as new is 1. A therapeutic globe, comprising an evacuated receptacle having an enlarged filament chamber provided with a flat end portiori, 'and a filament mounted within said chamber in a plane having spaced parallel relation to said fiat end portion.

2. A therapeutic globe, comprising an evacuated receptacle having an enlarged filament chamber formed with a fiat end, and a filament formed of a flat strip of-Inaterial mounted in a plane within the chamber in v spaced parallel relation tosaid flat end.

3. A therapeutic globe, comprising an evacuated receptacle having an enlarged filament chamber formed with a fiat end portion of uniform thickness, and a filament mounted in said chamber and extending within a single plane in spacedparallel relation to HUGH c. BURRUS.- GEORGE A. TORRENCE.
